Tensile Strength Assessments of CFRP Adhesive Bonded Joint

Abstract

In this paper, stress distribution analysis and tensile strength assessment of CFRP bonded joint were studied. First a mixture of Epoxy adhesives and MWCNT was fabricated. Since failure is initiated at the ends of overlap, the stress distribution at the ends of the overlap and bonded joint was numerically analyzed. After the stress distributions were analyzed based on the result obtained the experimental steps were followed to assess the tensile strength of bonded joint. The stress distribution analysis and the tensile strength assessment results showed an agreement that the geometrical factors directly affect the reliability of the bond.
